[FIXED] Firebase "Failed to convert a value of type java.util.HashMap to int"

Issue

At this line of my code in my OnDataChange() method in the ValueEvenListener:

int latest = dataSnapshot.getValue(Integer.class);

I'm getting a DatabaseException with the error Failed to convert a value of type java.util.HashMap to int.

However, in my database, you can take a look at the image below:

It is obviously not a HashMap but an int. Is this a bug or am I doing something wrong? What can I do to fix it? Why is it retrieving a Hashmap when the value is int?

Full dataSnapshot:

final DatabaseReference database = FirebaseDatabase.getInstance().getReference();
        database.child("Campaigns").child(key).child("count");
        database.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                int latest = dataSnapshot.getValue(Integer.class);
                button.setText(latest + "");
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {
                Toast.makeText(context, context.getString(R.string.error) + ": " + databaseError.getMessage(), Toast.LENGTH_SHORT).show();
            }
        });

Database:

Campaigns:{
  -JDKKDJIIDJFIDJKDK:{
      count:2432
   }
}

Solution

It turns out I had to child dataSnapshot to my destination again. E.g:

int latest = dataSnapshot.child("Campaigns").child(key).child("count").getValue(Integer.class);

By default dataSnapshot is actually my whole database.
